Does PostgreSQL transaction affects by the system time?
SOLUTION UNVERIFIED - 已更新 2014年十二月3日14:49 -
环境
- Red Hat Enterprise Linux 5
- PostgreSQL
问题
- Does PostgreSQL transaction affects by the time in the system?
决议
- PostgreSQL does not concern local time when the application handles its transaction. It means that PostgreSQL was not affected by the time jump.
- Even though the time jump does not affect PostgreSQL, you should maintain the time with ntpd for the analysis.

本文探讨了PostgreSQL在处理事务时是否受系统时间的影响。据Red Hat官方解答,PostgreSQL在进行事务处理时不依赖于本地系统时间,因此不会受到系统时间跳变的影响。尽管如此,为了便于分析,仍建议通过ntpd维护系统时间。
